If you’re using one of the new iMacs or MacBooks with Retina Display for Adobe Photoshop, you may have noticed that your images look very small when selecting, View–> Print Size.  That’s because the retina display has a MUCH higher resolution than the typical CRT or LCD monitor. Most displays have a screen resolution around 72 pixels per inch (ppi), which is far less than what you get with a retina display.

Get the fix here:

Here’s the fix for retina display users:

1. In Photoshop, open Preferences dialog.
2. Choose the Units & Rulers option
3. Set the screen resolution to 220 pixels/inch.

Now, when you select View–> Print Size, the image will display at the proper size.
